Description

Along with shoes, Giro saw the need for
better insoles. They so liked the results of their insole design work
that they're selling them as an after-market accessory, the SuperNatural Fit Kit.
Their goals were to make their insoles more comfortable for a wide
range of foot types, and that they'd offer enough adjustability to
perhaps negate the need for investing in custom insoles.

One of the few benefits of the wafer-thin insole that many shoe companies supply with shoes is that it is
wafer thin. No bulk in what is an extremely close-fitting shoe is most
often a good thing. This keeps the ball of the foot very close to the
sole and in turn the pedal spindle, minimizing stack height, and it
keeps the heel very low in the heel cup, maximizing the cup's ability to
hold the heel down. Giro started with these two benefits and added one
of the benefits of custom insoles; arch support. Arch support, is
critical for cycling comfort. When the leg pushes down on the foot, the
arch can flex, which can lead to shoe movement, which can lead to
alignment issues, to the foot moving in the shoe, to developing hot
spots.

Another benefit of custom and semi-custom insoles is a
"metatarsal button" that provides greater mid-foot comfort. Giro has
included a subtle button as they've found wide variation in individual
rider's ability to find such a feature comfortable.

The base of
the insole is a thin layer of EVA foam. It's thick enough that normal
use of the insoles will help to customize, or tune, or crush some of the
EVA so that you'll see divots in the foam after a few rides. This will
increase the surface area of contact points, which should increase
comfort, but the EVA is secondary to the three arch supports that come
with each insole.

There is a small, medium, and large arch. They
can be easily and quickly swapped in and out. The small maintains the
contour of the insole itself. The medium adds 3mm to the arch compared
to the small. The large adds another 3mm beyond the medium. These are
easy to use. First, in either bare or thinly-socked feet, place the
support under your foot. Try different sizes until you find one that
seems snug against your foot. You want it close because you don't want
your arch acting like a leaf-spring each pedal stroke. Figure out the
size. Ride. Adjust if necessary.

The insoles are covered with
X-Static fabric. The name is familiar because you've already seen Giro
and others use it in helmet pads. It's a silver, the mineral, fiber that
is bonded to a polyester fabric to make the fabric anti-microbial,
anti-stink.

You'll see that each size of the Giro SuperNatural Fit Kit
fits a number of size shoes. These are "trim to fit" insoles and
there's a cutting guide underneath each insole, but your best bet is to
either compare it to your stock insole or shove it inside your shoe
before commencing on any alterations.

Great value

I've put it through the wringer

I wear a SIDI wire vent shoe in size 43. The stock insoles do not accommodate my mid-rise arch. I have used the Specialized medium insole and found that to be better. The Giro insoles need less trimming to fit, at least for the SIDI 43 - just follow the line. Good support and I like being able to try the other arch options. They even come with an Extra high option that I have not seen with Specialized. Also provides the ability to have different arch heights if required for each foot. I have not ridden in extremely hot weather yet but so far no ventilation issues. I would purchase again and recommend others to try them, especially if you find your current insole lacking.

Just what I needed

For those of us with odd or problematic feet we search for relief from our various ailments. The particular benefits for me is the metatarsal button which relieves a painful spot under the ball of my right foot. And the interchangeable arch supports. I use a medium on the right and a small on the left. Finally being able to "tune" an insole has been great.

Installation of these in my Bont Vapor shoes took 92 seconds of effort.

Not sure if you have been to Podiatrist for your foot pain, but I recently went after have the same problem of pain in the ball of my foot and I was diagnose with a Morton's Neuroma. I am waiting to have surgery until riding season is over. I am going to try these insoles to get me through. https://en.wikipedia.org/wiki/Morton%27s_neuroma

Great alternative to Superfeet

I have typically used black superfeets for insoles and they have worked well. I wanted more arch support than what was in the Superfeet, but I would have to compromise and get an insole that was thicker in the superfeet to have adequate arch support. With these, I can fine tune the arch support and still keep the thin insole.

I also use Giro shoes, so it was a no brainer and fitting these insoles in their own shoes were perfect, not that trimming for other shoes would be an issue.

Changing the arch support is easy and the velcro holds the support in place and doesn't move.

I had foot pains with the stock insoles, but have had no pains during 15-20 mile mountain bike rides. Time will tell on how comfortable they are during longer rides, but initial impressions are great!

Nice inserts

I had to replace them when I threw my last pair in the dryer (bad idea, by the way). Nice insert to help keep me in the saddle for 100+ mile rides. These are quality inserts - highly recommended (even if they can't be dried).

Worth every penny

I have a pair of Fizik R3 shoes that fit quite well, but I was having foot pain on longer rides. My feet are pretty normal, if a touch wide, but my arches have gotten fairly high after a few years of wearing low-support/minimal shoes. I dropped these insoles in, with the highest-support attachment, since that's what I use in my Giro mountain shoes. I rode about 50 miles in them today, with virtually no foot pain. The arch-size inserts attach using a double velcro, and I've never had it slip in my mountain shoes, and don't expect it to in these. You can trim them to fit fairly easily by matching your shoes' insole to the Giro version, drawing a line, and getting after it with some scissors.

Hello, I am looking for foodbed for my...

Hello, I am looking for foodbed for my boyfriend. His feet got hurt when he walks more often, especially at the heel. Do you think this product can help hm? Can this product fit inside every kind of shoes? He wear size 9, can you teld me what size of the foodbed I should buy

You have to take out the inner shoe sole that comes with the shoe to get them to fit. Most shoes you can easily remove them. Some are glued. These will help if you have plantae fasciaitis or other arch pain.
